I taken a few trips to the Boundary Waters Canoe Area (BWCA) in Northern Minnesota, and I would go yearly if I could. It is an amazing place. Patagonia has a neat blog post about a couple conservationists who paddled their way to Washington DC from the BWCA to raise awareness about a potential mining operation that could threaten some of the ecosystem in the National Wilderness Area.
Take a peak at the video. If it is something that moves you, read the blog and consider signing the petition to protect the BWCA at this link HERE.
